_ClassType FileList

A list of files built by on exploring the filesystem and filtered by
applying various patterns to what we find there.
Instance attributes:
dir
directory from which files will be taken -- only used if
'allfiles' not supplied to constructor
files
list of filenames currently being built/filtered/manipulated
allfiles
complete list of files under consideration (ie. without any
filtering applied)

include_pattern(self,
pattern,
anchor=1,
prefix=None,
is_regex=0)

Select strings (presumably filenames) from 'self.files' that match
'pattern', a Unix-style wildcard (glob) pattern. Patterns are not quite
the same as implemented by the 'fnmatch' module: '*' and '?' match
non-special characters, where "special" is platform- dependent:
slash on Unix; colon, slash, and backslash on DOS/Windows; and colon on
Mac OS.

If 'anchor' is true (the default), then the pattern match is more
stringent: "*.py" will match "foo.py" but not
"foo/bar.py". If 'anchor' is false, both of these will
match.

If 'prefix' is supplied, then only filenames starting with 'prefix'
(itself a pattern) and ending with 'pattern', with anything in between
them, will match. 'anchor' is ignored in this case.

If 'is_regex' is true, 'anchor' and 'prefix' are ignored, and
'pattern' is assumed to be either a string containing a regex or a regex
object -- no translation is done, the regex is just compiled and used
as-is.

Selected strings will be added to self.files.

Return 1 if files are found.

exclude_pattern(self,
pattern,
anchor=1,
prefix=None,
is_regex=0)

Remove strings (presumably filenames) from 'files' that match
'pattern'. Other parameters are the same as for 'include_pattern()',
above. The list 'self.files' is modified in place. Return 1 if files are
found.
